摘要: 对塔里木盆地火山岩、 生物礁、膏盐、金属非金属)矿床、地层水等分布及特点进行了分析和讨论,认为盆地有深部流体活动。沥青中的Pb、Sr、Nd同位素研究揭示了沥青是深部流体形成的,而上地壳寒武-奥陶纪沉积的有机质并没有参与生烃过程。盆地的深部地壳结构特征也支持塔里木盆地的油气可能是由深部地幔流体的费托合成反应而生成。

Abstract: The occurrence and characteristics of volcanic rocks, organic reefs, gypsum-salts, metal (non-metal) deposits, formation waters in Tarim basin are discussed. The results show that there exist active deep geofluids in the basin. Pb-Sr-Nd isotopic systematics of the bitumen and trace elements of the crude oils support the deep inorganic origin of the bitumen and crude oils. The deep crust structure of the basin shows that petroleum can be formed in the low velocity-high conductive layer by Fischer-Trupsch synthetic reaction.

Key words: volcanic rock, organic reef, evaporate bed, deep zone, fluid, trace element, asphalt, inorganic origin
